Description

Technical Field

[0001] This utility model relates to the field of kitchen waste technology, and in particular to a kitchen waste separation device. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and institutional catering activities, including discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc. Currently, the high-protein, nutritious components of kitchen waste can be converted into feed for black soldier flies, which can then be used as animal feed. Their excrement can be used as fertilizer for the soil, and the entire process is pollution-free.

[0003] To improve the quality of feed production, kitchen waste needs to be separated. Currently, most separation methods are simple solid-liquid separation, leaving a lot of grease residue in the solids. Furthermore, the subsequent treatment of the oil and water is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where a significant amount of grease remains in the solids after solid-liquid separation, and subsequent oil and water treatment is inconvenient. Therefore, this invention proposes a kitchen waste separation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A kitchen waste separation device includes a processing box, a feeding mechanism on one side of the processing box, and a separation mechanism inside the processing box;

[0007] The feeding mechanism includes a feeding trough inclined above the processing box, a feeding hopper above the higher side of the feeding trough, a collection hopper connected through the discharge end of the feeding trough, and a vibration component for driving the feeding trough to vibrate. The feeding hopper is mounted on the processing box by a bracket.

[0010] More preferably, a protective cover is provided on the outside of the vibration motor.

[0011] Preferably, a spray assembly is provided above the feeding trough. The spray assembly includes a spray pipe horizontally arranged on the higher side of the feeding trough, a water inlet pipe connected through the spray pipe, and a water pump for supplying water to the water inlet pipe. The water pump's inlet pipe extends through the side wall of the treatment tank to the lower part of the clear liquid tank. Multiple spray nozzles are installed on the spray pipe corresponding to the feeding trough.

[0012] Preferably, a filter screen is provided in the water-permeable opening on the first partition.

[0013] More preferably, a drain outlet is provided on one side of the inner wall of the separation tank, penetrating the side wall of the treatment box, and a guide plate is provided on the bottom wall of the separation tank corresponding to the drain outlet.

[0014] Preferably, a flow-blocking plate is provided on the side of the processing box corresponding to the first partition and the second partition away from the feeding mechanism.

[0016] Preferably, there are two scraper blades 53, which are respectively arranged on the front and back sides of the steel strip 52.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by separating the solids in kitchen waste and then separating the oil and water, the separation of different materials in kitchen waste is realized, realizing multi-level recycling of kitchen waste and facilitating further processing.

[0019] 2. In this utility model, the separated clear liquid is used to spray the kitchen waste in the feeding tank to improve the separation effect of oil in the kitchen waste, avoid oil residue on solids, improve the separation quality, and facilitate subsequent processing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 A kitchen waste separation device includes a processing box 1. A feeding mechanism 2 is provided on one side of the processing box 1. The feeding mechanism 2 is used to feed in the kitchen waste to be processed and to separate solids from oil and water. A separation mechanism 3 is provided in the processing box 1 for separating oil and water.

[0029] The feeding mechanism 2 includes a feeding trough 21 inclined above the processing box 1, a feeding hopper 24 above the higher side of the feeding trough 21, a collection hopper 214 connected through the discharge end of the feeding trough 21, and a vibration component for driving the feeding trough 21 to vibrate. The feeding hopper 24 is mounted on the processing box 1 by a bracket. Drainage holes 211 are evenly distributed through the bottom wall of the feeding trough 21, and a discharge port 215 is provided on the outer side of the collection hopper 214. When feeding kitchen waste, the material falls onto the higher side of the feeding trough 21 through the feeding hopper 24 and falls with the vibration of the feeding trough 21. At the same time, residual water and oil in the kitchen waste are filtered down through the drainage holes 211. The solids are collected by the collection hopper 214 and discharged through the discharge port 215 for subsequent processing. To control the movement speed of the solids, a slow-fall strip 212 can be set on the inner bottom wall of the feeding trough 21, perpendicular to the direction of material movement, to improve the separation effect of liquid from solids.

[0030] The separation mechanism 3 includes a first partition 31 and a second partition 32 arranged sequentially from the side of the feeding mechanism 2 within the inner cavity of the processing tank 1, dividing the inner cavity of the processing tank 1 into a separation tank 41, a buffer tank 42, and a clear liquid tank 43. Both the first partition 31 and the second partition 32 have water-permeable openings 33 at their lower parts. The processing tank 1 is equipped with an oil removal mechanism 5 corresponding to the separation tank 41, and the clear liquid tank 43 has an outlet 431 on its outer side. Due to the difference in density between water and oil, the first partition 31 separates the oil on the upper part of the liquid surface, while the water gradually flows through the water-permeable openings 33 at the lower parts of the first partition 31 and the second partition 32 into the clear liquid tank 43, until it is discharged from the outlet 431, facilitating subsequent purification of the separated water. Simultaneously, the design of the buffer tank 42 ensures a good separation effect for the oil and a good oil removal effect for the clear liquid.

[0031] Based on the above technical solution, during the recycling and separation of kitchen waste, the kitchen waste is fed into the feeding trough 21 through the feeding hopper 24. A vibration assembly drives the feeding trough 21 to vibrate, causing the solid material to descend along the feeding trough 21 until it enters the collection hopper 214 and is discharged through the discharge port 215, facilitating subsequent recycling of the solid material in the kitchen waste. Simultaneously, the water and oil in the kitchen waste fall into the separation tank 41 through the drain hole 211. The oil is separated by the first baffle 31 and the second baffle 32 blocking the upper layer of oil. At the same time, the oil removal mechanism 5 removes the upper layer of oil from the separation tank 41, facilitating further oil treatment. The separated water is discharged through the liquid outlet 431 for further purification.

[0032] In this technical solution, such as Figure 1-4As shown, the vibration assembly includes a vibration motor 23 mounted on the lower end of the feeding trough 21, multiple cantilever arms 213 fixedly mounted on both sides of the feeding trough 21, support plates 22 on the processing box 1 corresponding to both sides of the feeding trough 21, and multiple compression springs 221 connecting the cantilever arms 213 and the support plates 22. The vibration motor 23 drives the feeding trough 21 to vibrate, and the design of the compression springs 221 supports it, ensuring the vibration effect of the feeding trough 21.

[0033] In this technical solution, such as Figure 1-4 As shown, a protective cover 231 is provided on the outside of the vibration motor 23. This protects the vibration motor 23 from the accumulation of oil and water on its outside, ensuring the stable operation of the vibration motor 23.

[0034] In this technical solution, such as Figure 1-5 As shown, a spray assembly 25 is provided above the feeding trough 21. The spray assembly 25 includes a spray pipe 251 horizontally arranged on the higher side of the feeding trough 21, a water inlet pipe 252 connected through the spray pipe 251, and a water pump 253 for supplying water to the water inlet pipe 252. The inlet pipe of the water pump 253 extends through the side wall of the treatment tank 1 to the lower part of the inner cavity of the clear liquid tank 43. Multiple spray nozzles are installed on the spray pipe 251 corresponding to the feeding trough 21. By drawing some water from the clear liquid tank 43 and sending it to the feeding trough 21 to spray the kitchen waste, oil is prevented from adhering to the solids, reducing oil residue on the separated solids and facilitating subsequent processing of the solids.

[0035] In this technical solution, such as Figure 1-3 As shown, a filter screen 34 is provided in the water-permeable opening 33 on the first partition 31. This filters particulate solids that fall into the separation tank 41, preventing the clarified liquid from containing too much solids and facilitating subsequent processing of the clarified liquid.

[0036] In this technical solution, such as Figure 1-3 As shown, a drain outlet 412 is provided on one inner wall of the separation tank 41, penetrating the side wall of the treatment box 1. A guide plate 411 is provided on the bottom inner wall of the separation tank 41 corresponding to the drain outlet 412. This facilitates the discharge of deposited solid materials and the cleaning of the treatment box 1.

[0037] In this technical solution, such as Figure 1-3 As shown, in the processing tank 1, a flow baffle 35 is provided on the side of the first partition 31 and the second partition 32 away from the feeding mechanism 2. The flow baffle 35 prevents the clear liquid from flowing directly to the liquid outlet 431, slows down the flow time of the liquid, and improves the purification effect of the clear liquid.

[0038] In this technical solution, such as Figure 1-5As shown, the oil removal mechanism 5 includes a motor 51 above the treatment tank 1 corresponding to the separation tank 41, a ring-shaped steel belt 52 sleeved on the output end of the motor 51, an oil scraper 53 disposed on one side of the steel belt 52, an oil collection trough 54 disposed below the oil scraper 53, and an oil outlet pipe 541 connected through the bottom wall of the oil collection trough 54. The lower part of the steel belt 52 extends below the liquid surface. The motor 51 is mounted on the top wall of the treatment tank 1 by a bracket. An avoidance opening is provided on the top wall of the treatment tank 1 corresponding to the steel belt 52. The oil scraper 53 is arranged on the side where the steel belt 52 moves downward, and there are two oil scraper 53s respectively arranged on the front and back sides of the steel belt 52 to ensure the oil scraping effect.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
